heavy duty battery cables

Dealer or welding supply. Some auto parts stores but not many.

 

Interstate batteries Dealer, they are in most places. They sell cables as well. we ordered cables 100 ft at a time at Interstate batteries. Batteries are $50 with the core as well next time you change your batteries. Ask for 1 AWG (american wire gauge) wire. They have the cable in your area. i called and checked for you.

Unless you know what you are doing, don't both, just get the old ones off, get new ones made from them with the properly sealed ends - it saves headaches in the long run.

 

You will have better luck using #2 cable and doubling them up to the starter and grounds. The really big cable gets so stiff it will break things.
What I do is solder the ends on then coat with gasket sinch, then shrink tube. I always recomend after the batteries are charged independently with a regulated charger, and everything is put back together, you turn on all the lights and put it to 1200 RPM and then take a voltmeter from the alternator ground to the right frame rail. If you have over .2 volts make a #4 cable up. It is amazing how many units will get codes and that little fix will cure it.
Just a thought!

 

BTW he said #1AWG cable is no more than $4 a foot. well worth it if you ask me, and your welcome. Figured id put in some work lol
